Little Black Bugs

I know it’s probably hard to tell from the picture, but can’t hurt to ask. Does anyone know what these little black bugs are? They appeared all over the surface of my pool today. They seem to clump up on the water surface.

I get them from time to time as well, just like the flying ant groupings 2-3 times per year. I'm no entomologist, but those little gnat-things come out of nowhere. Thank goodness for skimmer socks.
